Nginx，PHP-FPM，Symfony，Docker，为用户运行多个页面的可能性

Question

Im looking for a setting that affect the ability to run multiple nginx processes for one user. Currently, if administrator preforms a long time operation (upload multiple files) there is no possibility of openning the page in another tab - the page is waiting until the first tab ends.

This is my docker-compose

version: "3.1"
services:
 webserver:
      image: nginx:alpine
volumes:
          - .:/application
          - ./nginx/nginx_all.conf:/etc/nginx/nginx.conf

This is nginx_all.conf

user nginx;
worker_processes  1;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log /dev/stdout  main;

    #sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;


 server {


   #  limit_conn conn_limit_per_ip 10;

   #  limit_req zone=req_limit_per_ip burst=10 nodelay;

fastcgi_keep_conn on;
#proxy_buffering off;
gzip off;


     listen 80 default;

     client_max_body_size 208M;

     access_log /var/log/nginx/application.access.log;

     root /application/public;

     rewrite ^/index\.php/?(.*)$ /$1 permanent;

     try_files $uri @rewriteapp;

     location @rewriteapp {
         rewrite ^(.*)$ /index.php/$1 last;
     }

     # Deny all . files
     location ~ /\. {
         deny all;
     }

     location ~ ^/(index)\.php(/|$) {
         fastcgi_pass php-fpm:9000;
         fastcgi_split_path_info ^(.+\.php)(/.*)$;
         fastcgi_index app_dev.php;
         send_timeout 1800;
         fastcgi_read_timeout 1800;
         fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
         fastcgi_param PHP_VALUE "error_log=/var/log/nginx/application_php_errors.log";
         fastcgi_buffers 16 16k;
         fastcgi_buffer_size 32k;
         include fastcgi_params;
     }

     # Statics
         location /(bundles|media) {
         access_log off;
         expires 30d;
         try_files $uri @rewriteapp;
     }}

}

i try change - worker_processes 1; to worker_processes 2; - but that does not change behavior.
